MC7354 MAIN/AUX antenna selection in factory test mode

IoT Modules MC/EM Series

Hello,

We want to perform simple Max Power tests on each antenna separately. Is it possible to switch between MAIN/AUX antennas to perform Max. Power Measurement Test?

Thanks,
Sagar

Sagar,

The short answer is no because the unit only supports MIMO in receive hence the unit only transmits out of the main.

OK, thanks Matt.

Where can I find the right sequence for the AT commands to perform an RX test reporting RSSI/antenna port? Also, if I have to transmit an appropriate waveform from another MC7354 to perform this RX test, if you can share the AT sequence for it, will be helpful.

Thanks!
Sagar

Sagar,

This is discussed in appendix C of the PTS at the link below and you use a signal generator for the receive test, not another MC7354.
